Abstract
The invention provides a PU shoe sole laminating and forming process which comprises the following steps of: flatly putting film paper on a bottom mould of a mould, and pressing a middle frame to cover the bottom mould, and fixing by tensioning hand fasteners; carrying out vacuum-pumping on an inner cavity of the mould and enabling the film paper to completely fit to the bottom mould; heating the mould for increasing the mould temperature to 60-70 DEG C; and finally, pouring a polyurethane foaming stock solution into the mould cavity for foaming and forming the polyurethane foaming stock solution in a mould cavity, and cooling and de-molding, thereby obtaining the laminated PU foamed shoe sole. The PU shoe sole laminating and forming process can effectively solve the problems of bubbles, material deficiency, foamed grains, pits and pores generated in a PU foamed shoe sole production process, so that bright effect of products is improved.
Description
Technical field
The present invention relates to a kind of sole processing process, particularly relate to a kind of PU sole overlay film moulding process, belong to sole and add
Work field.
Background technology
It is low that PU (polyurethanes is called for short polyurethane) sole has density, good springiness, and compression ratio is good, it is not easy to deformation,
The irreplaceable advantage of the other materials such as good stability of the dimension.Its product process poly-be foamed by chemical reaction by liquid charging stock and
Generating, general employing polyurethane two-component liquid reactions moulding process, the main chemical reactions of this technique includes that gel heat release is anti-
, should be foamed the endothermic reaction and cross-linking reaction, in course of reaction, making of material temperature, mould temperature, ambient temperature, catalyst and foaming agent
With, all can affect effect and the sole quality of foaming, need to control well gel reaction and two balanced types of foamable reaction, to reaction
Condition requires strict, otherwise there will be bubble, lacks material, the foaming problem such as stricture of vagina, pore, and these all can only be by producing follow-up people
Work is repaired, is sprayed paint and make up, but effect is limited, and manual repair, and time long cost is high.
Summary of the invention
It is an object of the invention to provide a kind of PU sole overlay film moulding process, it is intended to solve existing PU foamed shoe sole and make
During, need manual repair, the problem producing follow-up flow process such as spray paint.
Technical scheme is as follows:
A kind of PU sole overlay film moulding process, specifically includes following steps:
Step (1): one film paper of smooth placement on the bed die of mould, then presses center and covers bed die, buckle hands
Button is fixing；
Step (2): dies cavity is carried out evacuation, makes film paper fit completely bed die；
Step (3): mould is heated, makes mold temperature reach 60 DEG C-70 DEG C；
Step (4): filling polyurethane foaming stock solution carries out foaming, and the heat produced during by foaming in die cavity
With pressure, film paper is fitted tightly further, after foaming terminates, cooling and demolding, i.e. can get the PU foamed shoe sole of overlay film.
Above-mentioned PU sole overlay film moulding process, in step (1), described film paper is PU film or TPU membrane, and thickness is 0.025-
0.045mm。
Above-mentioned PU sole overlay film moulding process, in step (2), the vacuum of vacuum maintains 0.05-0.1mbar
In the range of.
The invention has the beneficial effects as follows:
1, the present invention is first at mold bottom die upper berth thin film paper, and after making it adsorb on bed die, reinjects PU foaming
Material foams, and utilizes the heat and pressure produced in foaming process so that film paper and PU expanding foam solution are bonded in one naturally
Rise, after cooling and demolding, make the PU sole of surface coating.The thin film paper due to the Surface coating in original PU foamed shoe sole,
The PU sole profile obtained smooths attractive in appearance, not there are the problem such as bubble, pit, it is not necessary to manual repair, saves significantly on artificial one-tenth
Basis and time, improve speed of production.
2, the present invention selects the film paper that thickness is less, it is not necessary to heat, film paper just can well docile at mould
Tool surface, energy consumption is low, and the decorative pattern on film paper surface is clear, has third dimension.
Additionally, the present invention is when carrying out evacuation to dies cavity, the vacuum ranges of control, so that film paper is tight
Patch mould and decorative pattern are clear, meanwhile, also film paper will be caused to rupture because pressure is excessive.
Detailed description of the invention
For making the purpose of the present invention, technical scheme and effect clearer, clear and definite, below give an actual example further to the present invention
Describe in detail.Should be appreciated that specific embodiment described herein is only used for explaining the present invention, be not intended to limit the present invention.
